Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for automatically generating enhanced caller identification data are disclosed. In one aspect, a method includes the actions of receiving telephone call placement data that indicates the placement of a telephone call from a calling party to a called party. The actions further include receiving caller identification data. The actions further include accessing first telephone call data that reflects characteristics of telephone calls placed and received by the calling party. The actions further include based on the first telephone call data and the identity of the calling party, determining additional data to combine with the caller identification data. The actions further include generating enhanced caller identification data by combining the additional data with the caller identification data. The actions further include providing, for output, the enhanced caller identification data and data indicating the telephone call.

In some implementations, a device may receive a SIP invite associated with a call to a first user device from a second user device. The first user device may be associated with a first network and the second user device may be associated with a second network that is separate from the first network. The SIP invite may include an identity header that indicates a carrier identifier associated with the second network. The device may authenticate the call based on a caller identification associated with the second user device and the carrier identifier. The device may send, based on authenticating the call, the SIP invite to the first user device to indicate, in association with receiving the call and via a user interface, an authorized entity associated with the carrier identifier according to the SIP update.

According to an embodiment of the disclosure, a toll-free telecommunications validation system determines a confidence value that an incoming phone call to an enterprises' toll-free number is originating from the station it purports to be, i.e., is not a spoofed call by incorporating one or more layers of signals and data in determining said confidence value, the data and signals including, but not limited to, toll-free call routing logs, service control point (SCP) signals and data, service data point (SDP) signals and data, dialed number information service (DNIS) signals and data, automatic number identification (ANI) signals and data, session initiation protocol (SIP) signals and data, carrier identification code (CIC) signals and data, location routing number (LRN) signals and data, jurisdiction information parameter (JIP) signals and data, charge number (CN) signals and data, billing number (BN) signals and data, and originating carrier information (such as information derived from the ANI, including, but not limited to, alternative service provider ID (ALTSPID), service provider ID (SPID), or operating company number (OCN)). In certain configurations said enterprise provides an ANI and DNIS associated with said incoming toll-free call, which is used to query a commercial toll-free telecommunications routing platform for any corresponding log entries. The existence of any such log entries, along with the originating carrier information in the event log entries do exist, is used to determine a confidence value that said incoming toll-free call is originating from the station it purports to be. As a result, said entities or enterprises operating a toll-free number may be provided a confidence value regarding an incoming telephone call, and using that confidence value, further determine whether or not to accept the authenticity of the incoming telephone call and/or based on said confidence value, service the incoming call differently.

A computer captures a voice of a user. The computer determines a frequency spectrum and a voice pattern of the voice. The computer identifies one or more topics of the voice by transcribing the voice by a natural language processing. The computer identifies the user based on matching the frequency spectrum of the voice to the frequency spectrum of the conversation and the pattern of the voice to the pattern of the conversation when a conversation is intercepted and determines a trust score based on comparing the one or more topics to the one or more topics extracted from the conversation.

A system for managing a conference call, the system comprising a call answering server configured to receive a call from an attendee device that has been forwarded from a host device, identify a conference call associated with the host device for the attendee device to join, receive a request from the attendee device to join the conference call, and connect the attendee device to the conference call.

The technologies described herein are generally directed to modeling radio wave propagation in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include, facilitating, by a first device, receiving a first communication directed to a second device from a third device associated with a first telephone number. The method can further include determining, by the first device, that the first communication comprises a reference to a second telephone number different from the first telephone number, resulting in a number discrepancy. Further, based on the number discrepancy and an analysis of the first communication, the method can further include preventing, by the first device, communication of the first communication to the third device.

A method for protecting subscriber data includes intercepting network traffic associated with a call. The network traffic includes call parameters and call stream data. A first set of the call parameters is analyzed. A first probability value of the call being declared as unwanted is determined. The call stream data is analyzed to define a second set of call parameters. The first set of call parameters is reanalyzed based on the second set. A second probability value of the call being declared as unwanted is determined. A determination is made if the second probability value exceeds a second threshold value. The call is declared as unwanted, in response to determining that the second probability value exceeds the second threshold. The first and second sets of call parameters are transmitted to an application configured to protect data of a protected subscriber.

Origin information for promotional calls is provided by recording caller numbers for parties making the promotional calls; and receiving subscriber numbers for receiving the promotional calls. The subscribers numbers are stored in a database that also includes approved content for the promotional calls to be received by the subscriber. Caller numbers and approved content are matched for the subscriber with a call scrubber including a disturbed ledger. The distributed ledger recording a caller designation attached to the caller numbers indicative of a type for the promotional call. A promotional call is received by the subscriber. The caller identification for the subscriber indicates both the caller numbers and the caller designation that is indicative of the type for the promotional call.

Aspects of the subject disclosure may include, for example transcribing a voicemail message left by a call originator and intended for a call recipient. The resulting text is scheduled to be delivered as an SMS message to the call recipient. The source phone number in the SMS message is set to the call originator’s phone number so that the transcribed voicemail text appears in a messaging application’s conversation view between the call originator and the call recipient. Other embodiments are disclosed.

Embodiments may provide techniques to screen for, detect, and prevent connection of robocalls. For example, in an embodiment, a method, implemented in a computer system comprising a processor, memory accessible by the processor, and computer program instructions stored in the memory and executable by the processor, may comprise receiving, at a telecommunications switch, a request to initiate a call from an originating party, selecting, at the telecommunications switch, from a list of terminating carrier networks, a media server, routing, at the telecommunications switch, the request to initiate the call to the media server, forwarding, from the media server, a media prompt requesting the originating party to enter a response to the media prompt, and when the originating party does not enter a correct response to the media prompt, forwarding, from the media server, an indication that the call is forbidden.
